Abstract
A method for controlling power supply in a buffered modulation mode is to control an inverter to perform energy transformation so that the inverter and a load in the rear end can function in a reliable characteristic range and prevent the load from aging too quickly. The method includes entering a total energy control regulation signal to an input end of an energy/time ratio synthesizing control unit to get an ON_OFF (High-Low) control sequence on output ends thereof, and adding a regulation energy of varying amplitudes during the ON-Time in the burst period of two ON_OFF cycles to prevent the excitation dynamical ratio of the inverter from being excessively large thereby to prevent the load from aging too quickly.
Claims6
A method for controlling power supply in a buffered modulation mode to control an inverter to perform energy transformation, comprising:
- generating an ON_OFF(High_Low) control sequence having an ON Time TA and an OFF Time TB in a cycle;
- and
- adding a regulation energy of varying amplitudes during a transition of the ON-Time in a burst period of two ON_OFF cycles to prevent a an excitation dynamical ratio (EDR) of the inverter from being excessively large to allow the inverter and a load on a rear end to operate within a reliable characteristic range.
